IMPROVEMENT m sub-mom HEATERS;

Be a known that I, JOSEPH W. room, of unnborou'gh Bridge, in the county of Hillsborough and State of New Hampshire, have invented anew and useful Improvement in Heating Sad-Irons; and I do J hereby declare that thefollowingis a full and exact (loseriptio'n thereofirefereuce being bad to the accom panying drawing and to the letters ofreicrence marked thereon.

In the accompanying drawing- Figure l is-a side view of my improved sad-iron.

Figure 2 is a view oi. the bottom or face plate of my improved iron.

Figure 3 is a view of a perlbratedplate which di-' vides the iron in two compartments,

Figure 4 shows the position of the tion to the face-plate of the iron.-

- My invention consists -First,of an arrangement of one or more gas-tubes burner in relaprovided with air-holes, and also with an obliquemouthed burner; and v Second, in the combination. of such tube or burner with a series .of escape-holes at the upper and outer corners of the chamber of the iron.

In the construction of my improved sadiron, a

suitable face-plate, A, fig. 2, is first made with two shanks, B, for attaching-the handle, and a stem, 0,

for supporting the burner. I

This plate A also 'has projections'l), for supporting the perforated plate E, fig. 3. v

Both of these plates are-connected with the jacket N, as seen in fig. 1, the face of the plate A thus forming the face of the complete iron \vhonput together, and the plate I l being iuc losed in the jacket,

as indicated in dotted lines in fig.

.An arm, G, is fastened to the stem U, for holding the tube H of the hunter.

' This tube H has two branches, which enter 'the jacket N, and extend down nearly to the face-plate A, where they terminate in a broad month,- made by removing the lower halt of the tube, as shown at 1, ii. 4.

In the branches of the tubes ii there are two openings K, for the admission of air and mixture of the same with gas, supplied by the rubber tube L to the tube H and burners.

'This rubber tube is provided with a coiled spiing, M, in order to prevent the-tube from folding too short over the end of the metallic tube H, with which the rubber connects, and thus stopping the flow of gas.

substantially as described.

This coiled spring gives the tube a gentle bend as the positiou of the sad-iron changes during its use.

The fresh air to feed the burner enters in part at K,- tig. 1, and. mixing with. the gas supplied by the tube H, passes to the mouth I, fig. 4, of theburner,

where the flame is directed upon the faceqilateA-of the iron. The sheet-ironjacket N has two series of holes, as seen at F and F, fig. 1.

This jacket, in connection with the pertbrated plate;

E, fig. 3, serves as a sort of chimney to'the burners,

admitting more orless air on the lower sideiu what'-' ever posit on the ironis turned in working; alsoj'allowing the escape ot the smoke on the upper side however the iron is turned.

If the iron be workiugupright, thedraught is upward through the plate E and out-ofthe holes F,

while some air enters at the lower holes F; and when the iron s turned on one side or even upside down,

the air enters belowand escape-s above;

The-perforated jacket thus tacilitates'the draught and combustion as the iron is turned in different positions, and also cuts elf any excessive current'of air and prevents the escape of gas, which would be very. oiiensivc. I,

If, upon Ttlltiltil" experiment, it is found necessary, oneor more vertical partitionsniny he insei'tedito further subdivide the chambers of the iron, but at pres: out I prefer the above-described.construction. The top of the iron is made of two plates of sheet metal, with an air-space between thcm as seen at P,

Having thus described my invention."

1. The tubes 11, provided with air-openings K, and also with oblique-mouthed burners, (or burners'having in directing shield above the flame,) for the purpose of bringing the flame or flames. directly upon both sides of thetransverse center of the .iEu-e-pla'te' of the iron, substantiallyas set forth.

2. In combination with the abovetubes or burner H, the series of escape-holes-.l or their equivalent, at the top and outer corners of the chamber of the iron, substantially as set forth. ,3. The arrangement of the perforated plate E, in combination with the face-plate A and the jacket N,
